Home > THE FRP PROCESS > SCT Tuning (X3 & X4)
If you have a 1996 through 2016 Dodge/Jeep/Chrysler product, read here for a walk-through on our superior tuning process.

If you're reading this, you are likely looking for tuning for your vehicle.
We primarily use SCT on 1996-2003 Jeeps, Dodge Trucks/SUVs, Viper 1996-2007 (includes SRT-10 Ram trucks) - these all use the "JTEC" controller. It is primarily identified by having 3 large black plastic connectors plugged into it in the engine bay.
SCT Programmers allows us to tune vehicles sight unseen, by tuning over email.
THERE IS NO MAILING BACK AND FORTH OF THE COMPUTER.

The process we use depends on how modified the vehicle is. For stock or lightly modified vehicles (cars/trucks with headers/exhaust, throttle bodies, cold air induction kits, no injector/camshaft/cylinder head modifications) we have our Canned Tunes. These are pre-loaded files we've put together, and in many cases have years of research and development behind them. They are octane-specific , and for certain engines we have towing-specific calibrations that are a little more conservative for pulling heavy loads. These require no datalogging- order through our website, wait patiently for the SCT Programmer to show up in the mail, plug into your vehicle, select the tune appropriate to the octane used/type of use, and enjoy. It really is that simple.

For those of you that have more serious modifications, like injectors, camshaft(s), aftermarket heads and/or head porting, forced induction/nitrous, etc, custom tuning is required... And with that, requires datalogging.
Datalogging is what makes FRP tunes so much more consistent from vehicle to vehicle than our competitors. Is it more expensive- absolutely- but it is totally worth it.
After verifying the vehicle is mechanically ready for tuning (more on this can be found in our Pre-Tune Checklist), and tuning is purchased, the end user needs to source a Wideband O2 sensor/gauge. A "wideband" as we refer to it as is simply a means of reading air/fuel ratio (we'll be referring to it as AFR from here on out). Especially under wide open throttle , we need to verify what the AFR is for best power, and for safe operation of the vehicle.
All custom tuning packages will be sent out with a base tune based on the items listed in our build sheet.
In almost all cases, the base tune should allow the vehicle to run, idle, and drive under very light throttle /low rpms, but will absolutely require immediate and thorough revising for safe operation.
With the X3 and X4 devices, we will be setting up datalogging through the SCT Livelink Gen II program , by establishing communication to the vehicle, selecting the appropriate channels (we provide a list for you) , connecting the wideband mentioned earlier with the SCT 9608 patch cable (purchased separately)
Because of the volume of vehicles we do, all custom tuning done over email will be done by an appointment basis.
By making an appointment, it ensures that there is no delays in waiting for Ryan to revise ones tune, and eliminates the chances of one "dropping the ball" with email tunes.
It is our goal to deliver a complete, and comprehensive tune as quickly as possible.

To make an appointment, contact us at ryan@frptuning.com ,or on the Flyin' Ryan Performance Facebook page (www.facebook.com/flyinryanperformance) and we will set up a tuning session.
We will expect the vehicle to be ready for tuning, with datalogging already set up and wideband installed.
A naturally aspirated car/truck should typically take no more than a 4 hour session. A forced induction vehicle should take approximately 6 hours.
Vehicles that have issues or are not prepared for tuning will go directly towards the back of the queue for additional tuning. It is VERY important that the vehicle is 100% ready for tuning.
If there is any questions about what is required to be ready, please reach out to us, we want to set you up for success so this can be an easy and painless process.
